The super clamp is designed to grip objects with a diameter of 0.6" to 2.4" (14-60mm), making it ideal for flat surfaces like desks and tripods, as well as cylindrical items such as selfie sticks, light stands, and bike handlebars. It features two 360° rotatable ball heads on a 3" (7.62cm) magic arm, allowing for flexible angle adjustments for optimal shooting. The screw knob enables quick fastening of the ball heads. Made from a durable aluminum alloy and stainless steel hybrid, the clamp is heavy-duty and scratch-resistant, with non-slip rubber pads to enhance stability and protect your equipment.
